Speaker Installation VERTICAL PLACEMENT RECOMMENDATION Vertical placement of the M1 Active Mk2 as shown in Figure 3 is highly recommended. This position will simulate the soundfield that will be heard in most consumers' homes and (to a great extent) their cars. For this reason, even if the M1 Active Mk2s are positioned horizontally for all of the mixing, the vertical position should always be used in the final "playback check" mode. (See next section) There are a couple of possible drawbacks to vertical placement of a nearfield monitor relating mostly to room interaction effects. Vertical placement allows the M1 Active Mk2s to portray your mix with the widest and deepest soundstage possible, so many people in the control room have an image of the "sweet spot". However, this wide a dispersion pattern in a control room with walls in too-close proximity to the speakers can add strong reflections to the sound you hear, muddying your mix. Page 29 shows the control room placement/ distance recommendations, which should help you determine if your available recording space would work well with the M1 Active Mk2s set up vertically. 22 M1 Active Reference Manual
